Quote from Kaeporo;905687:
Additional mastery skills were added in order to foster character development and reward specialization. No longer can you drop ~500 AP on a destiny and obtain end-game effectiveness.
And since they arn't a MAJOR 200-300k ap sink (most around 150-160) and give more dmg and some stats, I really don't see why most people hate them. >.> Dmg is dmg, stats are stats, sooner or later you'll rank any and everything so why complain about something directly made to make you stronger?

aux equip slot added in. Near the top of the equipment part of the inv screen there is another button similar to that for weapon changes. You can put a helm, robe, gaunt, armor, accessories, and boots in this tab and switch your 'outfit'. This semi would/semi wouldn't make the decorative tab useless as this still gets the stats from the outfit.
Ex: I have my -mp use outfit on but I need to use my melee set. Normally I'd have to summon a pet or have the armor in my inv. With this you just hit a button and assuming it's in those slots, it will switch your entire set up. So I can go from my clothing -mp set to a heavy armor set I have enchanted for melee combat in a pinch. Your decorative slots still cover up this switch however.
New 'skill set up' slots added to the game. 2 for everyone and up to 5 for paying players. Simply click the button and you'll load up that skill set. These skill sets change both of your F key lists and 1 through = keys to the skills you have set for them. You can also select a weapon from your inventory to activate the switch.
Ex: You set up your 1 slot to change to a specific set up when ever you equip your Lance and when you equip your Flame Cylinder it changes the skills to something else. This MIGHT seem too much like other MMOs to some players (Though I've played like...12+ and not a single one has this function so if anyone wants to QQ about this idea please, show me one that uses this :-/)
Combat mastery to add a total of 5 def at rank 1. Knuckle mastery to add a total of 20hp at rank 1. Alch mastery to add a tad more SP, Magic Mastery to add a tad more mp and int, and Production mastery to add 5% more to life skills and 10 more SP.
Respite to heal wounds starting at rank 5.
Poison put on weapons now lasts longer.
"Magic" pets now get MM, bolt mastery, and the masteries but MM only to 9, Bolt only to A, and the masteries only to either B or A.
New upgrade paths to the Dragon Fang, Glory sword, Tri staff, and a few other weapons that only have a single path to upgrade.
Shields no longer have hidden def and protection but instead show it in their stat screen.
The gesture to sit and clap counts as resting.
Eating food such as apple, meat, cheese, ect. Now adds stats after eating less instead of an extremely large amount. (srsly, around 30+ apples and still no stats guys T,T)
Cooked food now sells to NPCs at prices depending on the rank of the food and the stars.
Event items can be stored in your special inv. Also an option to not take part in an event that will give you a god dam 2x2 item every 20min. >.>[/SPOILER]
